Note: - This source code has the connectionstring hard coded in the program itself which is not a good programming practice. For windows application the best place to store connectionstring is “App.config”.

Also note that the final block which executes irrespective that there is error or not. Thus ensuring that all the connection to the datastore is freed. Its best practice to put all clean up statements in finally block thus ensuring that the resources are deallocated properly.
